SPECIFICATION forming part of Letters Patent No. 752,336, dated February 16, 1904.

Application filed October 2'7, 1908.

To all whom it may concern:

Be it known that I, THEODORE W. FOSTER, a citizen of the United States,residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Lockets, of which the following is a specification.

This invention has reference to an improvement in lockets whereby the ring, the component parts of the snap, and asemiconcealed hinge are formed without the use of solder.

The object of my invention is to construct a semiconcealed hinge for a circular locket that will conform to the edge or circumference of the locket and have all the strength and rigidity of a straight hinge.

Afurther object of my invention is to form the component parts of the snap integral with the front and back frames of the locket.

A still further object of my invention is to form the ring of the locket integral with the back frame and to cover it with a tubular ring plated on the outside with precious or semiprecious metal.

Figure 1 is a front View of a locket, showing my improved ring and semiconcealed hinge, the knuckles of which are straight, but set at an angle to conform with the circular edge of the locket. Fig. 2 is an edge View of the locket looking at the hinge. Fig. 8 is a group View of the front and back frames and the bent wire forming the pintle of the hinge, showing the construction of the knuckles before the hinge is formed, the shape of the pintle, the construction of the snap, and the ring formed integral with the back frame. Fig. 4 is an enlarged detail View of the hinge, showing the front and back frames in the open position. Fig. 5 is an enlarged detail sectional view taken through the hinge of the locket, showing the locket closed. Fig. 6 is a detail sectional View similar to Fig. 5, taken through the snap of the locket. Fig. 7 is an enlarged perspective view of the cup-shaped blank forming the tubular ring. Fig. 8 is a detail face view showing the cup-sh aped blank in position to be formed into the tubular ring inclosing the ring on the back frame, and Fig. 9 is a detail view of the completed ring.

In the drawings, (0 indicates the front cover,

6 the back cover, 0 the front frame, (Z the back frame, 6 the hinge, and f the ring, of the locket. The front cover a and the back cover Z) are dished and shaped to form the case of a circular locket. They have the cut-away portions to and I) for the hinge and are secured to the front and back frames by solder or other means. The front and back frames have the circular depressed portions 0 and d, in which are secured the pictures by the usual transparent mica disks and retaining-rings. The hinge 0 consists of the knuckle 0 formed integral with the front frame 0, the knuckles (Z (Z formed integral with the back frame d, and the pintle 9, formed of wire to have the straight central portion and the straight ends 9 g bent at an angle to the central portion to coincide with the angle of the knuckles 03 (V, as shown in Fig. 4. The snap of the locket consists of the stamped-up teat d on the back frame (1, coinciding with the aperture 0 in the front frame 0 when the locket is closed. The ring of the locket is rigidly secured to the back frame (Z without solder by forming the interior ring (Z 4 integral with the back frame, as shown in Fig. 3. The blank it, having the cut-away portion It, is now placed over the interior ring (Z and formed into a tubular ring inclosing the interior ring, as shown in Fig. 9, forming the completed ring f of the locket.

In construction the knuckles of the hinge e are formed on the front and back frames over the pintle g at right angles to a line drawn centrally through the knuckles from the center of the frames and placed flush with the outer circumference of the locket, forming a strong and rigid semiconcealed hinge. The component parts of the snap are formed integral with the front and back frames. The

and the pintle g having the straight central portion g and the straight ends 9 g bent at an angle to the central portion to form a semiconcealed hinge, the knuckles of Which are set at right angles to lines drawn from the centers of the frames 0 and d through the centers of the knuckles, as described.

2. In a locket, the combination With the back frame (Z, of the ring cl formed integral with the back frame, and a tubular ring inclosing the interior ring (F, as described.

3. In a locket, the combination of the front cover (4 having the cut-away portion a, the back cover I) having the cut-away portion Z), the front frame 0 having the depressed portions 0', the knuckle 0 and the aperture 0 the back frame (Z having the depressed portion cl, the

knuckles (Z (Z the stamped-up teat d, and
